[0029] Referring to FIG. 1, the LCD includes a user connecting part 100,an input/output part 200 and an LCD module.

[0030] The user connecting part 100 includes a first input terminal 110for receiving a power voltage, a second input terminal 112 for receivingan image signal formatted in analog type from an external host system(not shown), a third input terminal 114 for receiving an image signalformatted in digital type from the external host system and a firstintegrated type connector 102 for outputting the power voltage and theimage signals to the LCD module 900 through a plurality of ports. Thefirst integrated type connector 102 is connected with the userconnecting part 100 by means of a flexible printed circuit board(hereinafter, referred to as an “FPC”).

[0031] The input/output part 200 includes a plurality of keys to controlfunctions of the LCD module 900 such as contrast, color, position ofscreen, image, brightness, mode of video, auto-configuration, systeminformation and power and so on. The input/output part 200 provideskey-input signals generated by a user toward the LCD module 900 throughthe user connecting part 100, receives responsive signals correspondingto the key-input signals from the LCD module 900 and indicates theresponsive signals to the user with an LED or the like. The user cancontrol the functions of the LCD module 900 with OSD provided on thescreen of the LCD module 900 instead of the plurality of keys.

[0032] The LCD module 900 includes an integrated board 300, a backlightinverter 400 and an LCD panel (not shown) and displays a predeterminedimage in response to the power voltage, image signals and control signalprovided from the user connecting part 100.

[0033] The integrated board 300 includes a first interfacing part 302, asecond integrated type connector 310, a control/power part, an LCDdriving part and an ADC/TMDS/scaler part. The integrated board 300receives the power voltage, the image signals and the control signal andprovides the power voltage to the backlight inverter 400 through thefirst interfacing part 302. The integrated board 300 provides the imagesignal formatted in the analog type and a gate signal to the LCD panelthrough driver IC 304. The driver IC 304 that is TAB (tape-automatedbonding) IC includes a data driver IC connected to a data line formed inthe LCD panel a gate driver IC connected to a gate line formed therein.The data driver IC provides a data signal to the data line and the gatedriver IC sequentially provides a gate signal to the gate lines.

[0035] As described above, since the power voltage, the image signalsand the control signals are provided to the LCD module 900 throughintegrated ports such as the first and second integrated type connectors102 and 310, there is no need to use cables for checking signals tocheck the operations of the LCD module 900 and the LCD, therebydecreasing production steps of the LCD. Also, the appearance of the LCDbecomes simple by using the integrated type connectors.

[0036]FIG. 2 is a view showing the first and second integrated typeconnectors shown in FIG. 1.

[0037] Referring to FIG. 2, the first integrated type connector 102 isconnected with the user connecting part 100 by means of the FPC and thesecond integrated type connector 310 is connected with the LCD module900. The first and second integrated type connectors 102 and 310 includea terminal for the power voltage, a plurality of terminals for the imagesignals formatted in the analog type, a plurality of terminals for theimage signals formatted in the digital type and a terminal fordownloading a program from the external host system, respectively.

[0038] In general, the image signals supplied from the external hostsystem have to be converted into a form corresponding to a resolution ofthe LCD. The scaler functions to convert the image signals into the formcorresponding to the resolution of the LCD and the program for theoperation of the scaler is downloaded from the external host systemthrough the first and second integrated type connectors 102 and 310.

[0039] The first and second integrated type connectors 102 and 310respectively have a hook and a hole so that the first and secondintegrated type connectors are easily connected with each other. It ispreferably that in a case where the first integrated type connector 102has the plug shape, the second integrated type connector 310 has thesocket shape.

[0040] The plurality of terminals connected with the first integratedtype connector 102 and the plurality of terminals connected with thesecond integrated type connector 310 are disposed on the same line.

[0041] Although the connector having a socket shape which is provided tothe LCD module and the connector having a plug shape which is providedto the user connecting part are shown in the figures, the connectorhaving a socket type and the connector having a plug type may beprovided to the user connecting part and the LCD module, respectively.

[0042] Further, a hook for connection is provided to the socket typeconnector in the figure. However, the hook for connection may beprovided to the plug type connector.

[0043] As described above, in the integrated type connector inaccordance with the present invention, the power signal, various imagesignals and control signals are applied to the plurality of terminalsthat are arranged on the same line. Therefore, the structure of theconnector is compact and the LCD module may be slimed.

[0044] Further, the integrated type connector in accordance with thepresent invention has a docking form. Therefore, when performing aninspection process for checking whether or not the LCD module and theLCD device are normally operated after manufacturing the LCD module andthe LCD device, the module or device is coupled to a correspondinginspection device (not shown) via a docking method so that the module ordevice are operated by automatically downloading a program from theexternal host system.

[0045] Also, since a specific port of the integrated type connector maybe used as a download terminal that receives the program needed to theLCD, it is able to easily standardize the hardware of the LCD.

[0046] Further, as described in the above embodiment, the conventionalLCD separately adopts input terminals for receiving the power voltage,image signals and control signals. However, in the present invention, byapplying the power signal or any various signals via the integrated typeconnector, the manufacturer may easily confirm the normal operation ofthe LCD. As a result, the inspection process may be simplified and anyadditional cost for separately providing a connector may be reduced.

[0047] Further, the user does not require any lines for supplying poweror applying various image signals to the LCD device, the LCD device maybe connected to a host system for the inspection via the integratedconnector. Thus, the assembling process may be easily performed.
